Abstract

The paper is concerned with design and experimental characteristics of efficiency of natural gas centrifugal compressor (CC) and driven gas turbine at different conditions obtained on the results of physical experiments conducted during full-scale tests of GPA-C-6,3А. Comparative analysis of CC design and experimental characteristics showed that it is observed the good agreement of design and experimental characteristics for compressor design condition. Data analysis showed that under CC design condition the commercial capacity 12.2 MMNCMD, pressure ratio 1.45, polytropic efficiency 85% are provided, and consumed shaft power is  6.17 MW meeting technical requirements. The paper also presents data on hydraulic pressure losses effect in air intake and exhaust ducts on useful power and efficiency of driven engine under nominal condition. Thermaltechnical characteristics were obtained upon turbine (being the part of the package) test results. Under power turbine power 6.3MW the turbine effective efficiency was 30%, and specific fuel rate was 0.24 kg/kW∙h. This data as well as operation parameters of TCA  being the part of back-to-back test rig is the initial data to  make up system characteristics  of the package to be researched
